In a stem for the bowl of a smokers pipe,

The principle of my invention relates to a dethe stem being channeled axially communicatvice positioned in the tip end of the mouth-piece ing with the bowl at its respective end of the of a pipe stem I, the said stem having a channel stem, the other end functioning as a mouth- 2 axially extending therethrough and communipiece, and the channel being enlarged a short 30 eating with a bowl 3 to which the said stem is distance inward at the mouth-piece end of the joined. Such channel stem and. bowl as comstem, a tube inserted within the enlarged pormonly arranged have no means to prevent moistion and being in length shorter than the inner ture from the mouth passing through the chanextension of the enlarged portion of the channel,

To tion of the channel and being positioned so the avoid such dissatisfaction, I enlarge the channel adjacent ends of said tubular members are spaced of the stem by boring in at the tip end of the apart, there being an aperture in the stem therestem axially with the channel for a short disbetween as a drain for the space, means externaltance as shown in Fig. 2, by which means a trap 1y arranged on each tubular member to be en- 40 3 is formed, and in which the moisture will colgaged by the wall of the enlarged portion of the lect while smoking the pipe, but drained therechannel, all substantially as shown. from through an aperture 5 positioned at the 2. In a mouth-piece portion of the stem of a underside of the mouth-piece as shown in the smokers pipe, the stem and mouth-piece being drawing, and to guard against moisture enterchanneled axially, the channel passing through 5 ing the end of the channel adjacent the trap, the mouth-piece portion of the stem being enthe same is accomplished by an annular flange 6 larged a short distance inward from the outer about the end of tube 1, the said flange extending end thereof, a flanged tubular element and a into the trap, being integrally formed on the end hollow plug inserted within the enlarged porof said tube, as shown in Fig. 2, the hollow 8 of tion of the channel, the adjacent ends of said 50 the said tube being axially aligned and in regplug and tube being spaced apart to form a trap istry with the said channel. there-between, and being so positioned, as to To install the said tube, I bore the stem to a align the outer ends of the mouth-piece portion depth so that the flange thereof will be spaced and plug, the trap being drained by an aperture inward from said aperture 5. transversely extending through the wall of the 55 To avoid excess discharge of moisture into the mouth-piece portion of the stem adjacent the bore above referred to, I have inserted in the trap.
